Periodic acid is used to accomplish what?

Explanation:
Periodic acid acts as an oxidizing agent in histology. In the periodic acid–Schiff (PAS) reaction, it oxidizes vicinal diols in carbohydrates (such as glycogen and other polysaccharides) to produce aldehyde groups. Those aldehydes then react with Schiff reagent to yield the magenta stain. So the key action is oxidation, which enables the staining step that follows. It’s not a reducing agent, it doesn’t stain by itself, and it isn’t a dehydrating agent.
